Wires for JTAG interface MUST not be longer 20 - 25 cm !!!

Buy a LPT socket like this



and with the help of a multimeter chk all the pin connections...and solder required wires accordingly to different pins.

Then solder other end of wires to GENE

Put that wire set of pin no 14 & 18-25 to the Ground of the GENE PCB

And do not use USB while doing this

u need male socket because PCs have LPT female sockets

something like this





i have seen many people in the mobile repairing shops flashing nokia phones without the battery
so the answer is NO, u dont need to use battery or some other power source
LPT will provide all the power needed

Please go to Dev/ Hack section, there is a thread for changing IMEI numbers elaborated, started by ameeth (a mod). I don't remember exactly where but its a stickey.
Best of luck
